I have a turn restrictions shapefile acquired from a municipality that I would like to use when I create a network dataset. I found these instructions from ESRI to do exactly this: http://desktop.arcgis.com/en/arcmap/10.5/extensions/network-analyst/migrating-a-turn-table-to-a-shapefile-turn-feature-class.htm
However, after converting the shapefile into a feature class and attempting to use the "turn table to turn feature class" tool, the file format is not accepted (.dbf) and yet the syntax provided here: http://desktop.arcgis.com/en/arcmap/latest/tools/network-analyst-toolbox/turn-table-to-turn-feature-class.htm shows .dbf as an acceptable format.
I have no idea how to proceed from here. I have attached the dataset I am working with along with this post.
Is there another way to convert my data?
